I have seen a big advert in the AsthmaUK magazine for a shiny metallic spacer called a Vortex. I want to make sure my child gets his proper dose of salbutamol and will travel to the furthest reaches of the universe to ensure he does. So I had a look on eBay to see if anyone was selling one these devices, but only one person was selling any kind of spacer at all, for a whopping 59 quid, in the States, and that one didn't look much different to the plastic teddybear thing we've already got.
Does anyone know anything about the psychadelically-named Vortex, such as why it should be any better than the plastic thing? And where does one purchase this space-age technology? And how much is it? Any more info would be gratefully consumed into the vortex of my swirling mind.
